It's (finally) getting hot out—and along with long afternoons outside and mornings in the splash pool, my kids have already started begging for popsicles. And ice cream. And anything else that's cool and loaded-with-sugar-and-coloring. And, as much as the occasional sugary treat is fine, I would prefer not to load my preschoolers up with sugar every time they get hot and thirsty. So, I asked my sister who is a registered dietitian to give me 10 supercool and refreshing kid snacks that are healthy, too. Best of all, all of these take less than 5 minutes to make so you can stay outside as long as possible.

1. Watermelon Agua Fresca: Chop 1 seedless watermelon into small pieces and then have your kids smash it in a big bowl with a potato masher. Put smushed watermelon into the blender with crushed ice and a squeeze of lime juice and blend until smooth.
